Zusammenfassung:An electrophotographic material consisting of a high-insulating base and a photoconductive insulating layer coated directly thereon, is exposed uniformly on the side of the surface of the photoconductive insulating layer, to lights which are absorbable by the photoconductive insulating layer. Then, corona ions with a desired polarity produced by a corona discharge unit are sprayed onto the surface of the photoconductive insulating layer while the surface of the photoconductive insulating layer is simultaneously exposed to corona ions with the opposite polarity produced by another corona discharge unit. Thus, a conductive layer is temporarily produced on the surface of the photoconductive insulating layer so that the photoconductive insulating layer is charged or sensitized.
